Thanks for all of your help!
I use the stable version(Armbian_23.2.1_Rock-5b_jammy_legacy_5.10.160_xfce-amazingfated_desktop), and following the instructions add ppa and install kodi. It works so much better, chromium-browser plays youtube 4K movies very well.
But when I add add-on for youtuber, I got errors like inputstream.adaptive not available.
I check like this:

But the problems is that package "kodi-api-inputstream" is not available at all.
Any hints?
